Introduction

Members of group 3 introducing themselves…

… each in their own language

As you can see, our group is awesome. We are three exchange students and two full-degree students. Three Italians, a Belgian and a Dane. No Swiss, but one French-speaking.

We have structured our solution so that everybody has done their own part and then we divided the remaining parts in the group so that everybody could contribute. The work has been managed through Github with limited conflicts.

Cristina

My name is Cristina and I come from Milan, Italy where I am studying Business Analytics and Big Data at Politecnico di Milano. Right now I am at HEC in Lausanne as an exchange student within the QTEM master’s network. During this months I will attend the following courses:

Class Time
Programming Tools in Data Science Tueseday 1:15 pm
Computational Tools for Actuaries Thuesday 8:30 am
Conceptual Modelling for Business Analytics Thuesday 1:30 pm
Data Analytics for Decision Making Friday 8:30 am

The things that I am passionate about are:

  • Sports: Volleyball, Skii, Surf, Wakeboard
  • Art: I love reading about art and going to exibitions, expecially about Contemporary Art
  • Music: I listen to Rock, Indie-rock and Electronic music and I love going to concerts and festivals
  • Travel: I like discover new cultures and meet new people

A fun fact about me is that I am super clumsy, I have the ability to drop everything I am holding and to hit everything that is around me. So don’t ask me to hold your phone or to take care of something precious if you don’t want it totally smashed :D

Cristina’s Favourite Quote

“Whenever humanity seems condemned to heaviness, I think I should fly like Perseus into a different space. I don???t mean escaping into dreams or the irrational. I mean that I have to change my approach, look at the world from a different perspective, with a different logic and with fresh methods of cognition and verification.”

Italo Calvino, Six Memos For The Next Millennium

I have different passions:

  • Reading: I think it is my greatest passion. I like to enter in new worlds and to live new lifes.
  • Music: I come from a family of musicians. I don’t have a favorite genre, I listen to every type of music.
  • Travel: I like to discover new cities and countries. Moreover, I found beautiful to visit a city where a book that I read was set, in this way I feel part of the story

A fun fact about me is that when I travel I found always (always!!) one of the main attraction of the city with a scaffolding that hides it. So my photos are always ruined by the work in progress.

Very little is needed to make a happy life; it is all within yourself, in your way of thinking.

Emil

My name is Emil and I am on exchange at HEC Lausanne this semester. Originally, I am on my 2nd you of Msc in Business Administration and Information Systems from Copenhagen Business School.

I generally find it easy to get passionate about vastly different things, but it always comes back to..

  • Football, which allows me to chill with mates, exercise and compete at the same time
  • Politics, which I could read about all day long
  • Travelling, as I love visiting new places. 2018 has brought me to:
    • Denmark (where I live when not on exchange)
    • Singapore
    • Malaysia
    • US
    • Germany
    • Czech Republic
    • Austria
    • Slovakia
    • Hungaria
    • Italy (twice)
    • Norway (tomorrow)
  • Case competitions, business and entrepreneuship

A fun fact about me is that my grandpa hasn’t written an encyclopedia of 18 volumes about the European litterature. Oh, and I don’t drink coffe (what?!).

This is my favorite qoute. You should try to translate it here.

“Verden har brug for flere ydmyge genier. Der er efterh?nden for f? af os.”

Enjoying the Swiss mountains

Enjoying the Swiss mountains

I’ll say yes to anything you offer me to do but I am particularly fond of

  • Theatre, where I can express myself in various ways
  • Running, which keeps me full of energy
  • Classical music
    • Brams
    • Litz
    • Beethoven
  • Tennis, which helps me fulfill my need for competition

I am also very good at learning new languages and therefore enjoy learning new ones. Unfortunately, I am talking about natural languages, my gift doesn’t seem to work as well with programming ones.

A fun fact about me is that my grandpa has written an encyclopedia of 18 volumes about the European litterature.

I dedicate my spare time to some hobbies: * practice sports, like tennis, skiing and swimming * read poems, and sometimes learn them by heart * travelling, preferably by car, since I love driving

dies nihil est. Dum versas te, nox fit. Itaque nihil est melius quam de cubiculo recta in triclinium ire. Vinus mihi in cerebrum abiit.

RMarkdown Syntax

  1. Show an example where the chunk option cache = T leads to a misleading answer:
a <- Sys.time() 
print(paste0("Today is the ", a))
[1] "Today is the 2018-10-10 00:12:39"
  1. Simulate 100 random samples from a standard normal distribution using the function rnorm(). Store these 100 values in a vector called x. Then, compute the empirical median, mean and variance of x. Are these results different from 0, 0 and 1 (their respective theoretical values)? Is this result surprising? Justify your answer.
x <- rnorm(n = 100)
median(x)
[1] -0.04169975
mean(x)
[1] -0.01310984
var(x)
[1] 0.8571051

\[\mathbb{E} \left[ var \left\{ \boldsymbol{\upsilon_1} \left(\boldsymbol{\widehat\theta}, n \right) \mid \boldsymbol{\widehat\theta} \right\} \right] = \mathrm{var} \left\{ \textbf{v}_1 (\boldsymbol{\theta_0} ,n) \right\} + \mathbb{E} \left[ \mathcal{O_p} \left\{ \boldsymbol{\mathbf{D}}_1 (\boldsymbol{\theta}^* ,n ) (\boldsymbol{\widehat\theta} - \boldsymbol{\theta}_0) , ... , \boldsymbol{\mathbf{D}}_p (\boldsymbol{\theta}^* ,n ) (\boldsymbol{\widehat\theta} - \boldsymbol{\theta}_0 ) \right\} \right] = \mathrm{var} \{ \textbf{v}_1 (\boldsymbol{\theta}_0 ,n )\} + \mathcal{O_p}(n^{-2})\]

\[ \large{ \mathbf{A} \equiv [ a_{i,j}]_{i,j = 1, ... , p} } \]

  1. Include the following text in blue: “Vérité dans un temps, erreur dans un autre”, Charles de Montesquieu
